Post subject:  problem with second tuner
up untill this point i have only played with single tuner boxes. I have a new 250 that requires new IVTV. and a soft 401 card. here is my question.

i did a fresh install of knoppmyth. In the setup portion i set to capture cards both to the same guide source. But it wants to know what card is /dev/video and /dev/vbi and so on.. I have no idea what card is set to what video and so fourth.
i did look at /var/log/dmesg and saw teh bttv is set to /dev/video0 , i didnt see anything about the haupauge.. is there one spot i can look so see all the data i need??

well they will be /dev/video0 and video1 if one is software and one is hardware it's easy to tell, because when you are on the sofware one the tuner option is television, and the hardware(pvr) the tuner option is tuner0.

im very lost.. :( i started fresh with a pvr250 set it up so it was working with 100z ivtv drivers.. but as soon as i add a software hauppauge 401 card.. nothing works.. just freezes blank screen when i click watch tv. and i dont know what inputs goto what card..

when working on either card uner mythtv-setup

if i select /dev/video (or video0) i can only select television under the input. so i gues this means the bttv card is attached to /dev/video and /dev/video0 but i dont know if sound is the same.. ie /dev/dsp0 when /dev/video0 and /dev/vbi0

there doesnt seem to be any further inputs for the haupauge. when i select /dev/video1 it wont let me choose inputs.. the strange thing is. .i had the pvr working perfect before i put in the 401. so it cant be drivers.

also if you know a howto for adding a second card.. let me know.. i saw one some months back.. but a search couldnt quite find it.. i must be using wrong verbage. :(

one side question i was over at #mythtv-users on IRC and someone told me that those two cards wont work together because msp3400.o will confilct with each other since they both use it.. can anyone confirm that the 401 and pvr 250 work fine together??

If you're using bootsplash, press <ESC> then the system starts to boot. It will show you the cards that the system "sees" . The first is vidoe(0) while the second is 1. The system is probably locking because you need to specify the card and tuner type.

I just added a new 2nd PVR250 a couple of weeks ago. Here are the notes I kept for myself to get it going. I use the coax input (tuner 0) for both cards. If you use the other input types then it will be different for you. I think they key is getting the /etc/mythtv/modules/ivtv setup right. That was the hardest thing for me to find the right combination of settings.

Get latest IVTV
(I am using ivtv-0.1.10-pre2-ck114k.tgz now, I found later ones so far cause jerkiness and audio probs)
cd /usr/local/lib/ivtv
mv driver driver.old
Untar latest ivtv
go into new ivtv directory
copy the driver folder to /usr/local/lib/ivtv cp -a driver/ /usr/local/lib/ivtv/
cd /usr/local/lib/ivtv/driver
make clean
make install
If get warnings about msp3400.0 file (I didn't) rename it to something else like .old
change /etc/mythtv/modules/ivtv to this:
alias char-major-81 videodev
alias char-major-61 lirc_i2c
options ivtv card=10,85 type=2,39
options ivtv tuner=-1,39
options msp3400 once=1 simple=1
add below ivtv msp3400 saa7115 tuner
add above ivtv lirc_dev lirc_i2c

now update-modules
depmod
reboot.
Another thing I did but you may not have to is when you setup your cards via mythtv-setup have them start on channel 3 (or 4 or whatever your input source is set to if needed). Then reboot again.

Now that I'm home I can better answer this...
Code:
more /etc/modutils/KnoppMyth

You should see something like this...
Quote:
include /etc/mythtv/modules/bttv0
include /etc/mythtv/modules/ivtv
include /etc/mythtv/modules/ivtv1

In this case, I have a Hauppauge WinTV 401 that is /dev/video(0) and a M179 that is /dev/video1. I know this because of bttv0 and ivtv1. If the M179 was /dev/video(0), I see something like this:
Quote:
include /etc/mythtv/modules/ivtv
include /etc/mythtv/modules/ivtv0
include /etc/mythtv/modules/bttv
include /etc/mythtv/modules/bttv1

If you have to specify card and tuner type, you'd do in the ivtv include. Let's take the first example. If the WinTV had a card value of 10 and tuner value of 39, include /etc/mythtv/modules/bttv0 would look something like this:

Quote:
alias char-major-81 videodev
options bttv card=10,2 type=39,-1
You can look at ElGordo's example for the other way around.

Post subject:  New Connexant 8800/8801 based Hauppage WinTV 401
I hope cesman or any of you other gurus have an answer, and I hope it something other than "that card is useless". It is a Hauppage WinTV 401, bought 3 or 4 days ago.

http://www.newegg.com/app/ViewProductDe ... 606&depa=0

Here is info I dug up:

lspci output abbreviated:

02:0d.0 Multimedia video controller: Conexant: Unknown device 8800 (rev 05)
02:0d.1 Multimedia controller: Conexant: Unknown device 8801 (rev 05)

scanpci output abbreviated:

pci bus 0x0002 cardnum 0x0d function 0x00: vendor 0x14f1 device 0x8800
Conexant Device unknown

pci bus 0x0002 cardnum 0x0d function 0x01: vendor 0x14f1 device 0x8801
Conexant Device unknown

dmesg output abbreviated, appears twice in a row:

bttv: driver version 0.9.15 loaded
bttv: using 8 buffers with 2080k (520 pages) each for capture
bttv doesn't support your Conexant 2388x card.

Myth back end log:

Starting up as the master server.
QSettings: error creating /.qt

VIDIOC_S_FREQUENCY: Invalid argument
Channel Listings is defined, but isn't attached to a cardinput.

Am I SOL? do I have to get another card?

I know this is not what you wanted to hear, but that card has the new tuner on it, and it is more or less useless until the cxwhatver it is drivers mature.

Post subject:  thanks for the quick reply
Even bad news is better than being frustrated and being afraid no ne has dealt with this in a satisfactory manner.

I did some further research.

Seems the best bet is either:

compiling the drivers from: http://dl.bytesex.org/releases/video4linux/

which probably involves using the 2.4.26 kernel and kernel sources

or

just using the 2.6 series (especially the newest ones) to begin with

question to cesman and anyone else involved in packaging knoppmyth:

Will Knoppmyth be repackaged with 2.6 kernels soon? Seems 2.4 is out of favor with driver developers if the pages given above is any indication, so it seems to make sense to go with a kernel that supports more tuners out of the box.

Yes.

So roughly what would the definition of soon be in this case? :)

Post subject: 
the next version R5 will have a 2.6 kernel.
